For more information about these Application Load Balancers are the foundation of our application layer load-balancing platform for the future. The solution that I follow was to create an application load balancer (ALB), after that, I created a more readable DNS in Route 53 using the DNS generated by the ALB. Q: Can I configure my Amazon EC2 instances to only accept traffic from Classic Load Balancers? In order to be valuable, virtual appliances need to introduce as little additional latency as possible, and traffic flowing to and from the virtual appliance must follow a secure connection. address to associate with the Elastic IP address. It would make sense, in that light, that traffic addressed to anything other than the ENI address would be dropped, because trying to double-NAT traffic bound for random source addresses seems beyond the design scope, if not impossible.
